Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654538, here are decompositions:

17 + 8654521 = 8654538
71 + 8654467 = 8654538
107 + 8654431 = 8654538
149 + 8654389 = 8654538
157 + 8654381 = 8654538
181 + 8654357 = 8654538
199 + 8654339 = 8654538
239 + 8654299 = 8654538

Showing the first eight; more decompositions exist.
